Original owner. 1 year old. Perfect condition. True high-end monitors with holographic soundstaging and jawdropping purity. Early on in the listening sessions, I weeded out a sonically-decaying Marantz SA-8001 CD player purely based on the phenomenal truthtelling of these speakers, something Monitor Audio and Dynaudio could not do.
Magnificent speakers that have been babied all the way, serial #s 49a and 49b. I've owned dozens of speakers and these are the finest of the lot. The finish and construction are second to none and the sound is pure, 3-dimensional, and free of strain, even at high volumes. They seemingly cannot be pushed beyond coherence and utter poise, at least when held within the non-ear-damaging SPL range (beyond which I never go).
This pair, ordered on demand from Brilon, is the special "plus+" version that has improved ceramic-foam damping and tweaked-out crossover elements, and the high-gloss pure black finish is something to behold, with its disappearing act and glowing tangential optics (like a true high-end piano finish).
Quite forgiving in terms of amplification - I've used these precocious beauties with Arcam, Krell, Yamaha, and Rega with uniformly excellent results. Highly revealing, but not finicky in any sense, and possessed of simply gorgeous sound and looks that obliterate any questions.
